Whoa, ok lots of suggestions. That's awesome thanks so much. So I will test the ground voltage as per Mr. Lincoln. That should let me know if the braided strap is still good.
I am leaning towards improper engagement as well. Any tips on trying to get it to engage fully? I mentioned earlier that the flywheel shows wear on the first 3/16s" of the teeth. Perhaps it's even less than that now?
